You've read the labels. You've seen the long, unpronounceable words. And somewhere in the back of your mind you've wondered: is this actually safe for my baby?
That instinct is worth listening to.
Most baby products on the market are marketed with soft colours, gentle messaging, and words like "pure," "mild," and "natural" but a closer look at the ingredient list tells a different story. Many conventional baby washes, lotions, and wipes still contain chemicals that can irritate delicate skin, disrupt hormones, or absorb into the bloodstream at higher rates than they would in adults.
Here's what to look for and why it matters.
Why Baby Skin Is More Vulnerable to Harmful Ingredients
Before we get into the list, it helps to understand why ingredients affect babies differently than adults.
Newborn and infant skin is thinner, more permeable, and still developing its protective barrier. This means ingredients absorb more quickly and more deeply into the body. The surface area of a baby's skin relative to their body weight is also significantly higher than in adults, so even small amounts of a harmful ingredient can have a proportionally greater effect.
Add to that the fact that babies put their hands in their mouths, are bathed frequently, and wear diapers that hold products against their skin for hours and it becomes clear that what goes on their skin really does matter.
Ingredients to Avoid in Baby Products
1. Synthetic Fragrance
Also listed as: Fragrance, Parfum, Perfume
This is arguably the most important one on this list. The word "fragrance" on a label is a legally protected trade secret, meaning a single ingredient called "fragrance" can contain hundreds of undisclosed chemicals, including phthalates, allergens, and known skin irritants.
Synthetic fragrance is one of the leading causes of contact dermatitis (skin rashes) in babies and is commonly found in baby washes, lotions, wipes, and laundry detergents. Even products labeled "lightly scented" or "baby fresh" can contain it.
What to do: Look specifically for products that say fragrance-free, not "unscented," which can still contain masking fragrances. If you want a scented product, opt for one scented only with essential oils in age appropriate, diluted amounts, and always check that those oils are safe for infants.
2. Parabens
Also listed as: Methylparaben, Propylparaben, Butylparaben, Ethylparaben
Parabens are preservatives used to extend the shelf life of cosmetics and personal care products. They are also endocrine disruptors meaning they can mimic estrogen in the body and interfere with hormonal development. Studies have found parabens in umbilical cord blood and breast milk, suggesting they cross biological barriers with ease.
While regulatory bodies continue to debate acceptable limits, many pediatricians and dermatologists recommend avoiding them in products used on infants, especially given how much more readily baby skin absorbs them.
What to do: Check the full ingredient list, parabens are usually listed near the end. Look for paraben-free products preserved with safer alternatives like sodium benzoate, vitamin E (tocopherol), or rosemary extract.
3. Sulfates (SLS and SLES)
Also listed as: Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Ammonium Lauryl Sulfate
Sulfates are the foaming agents responsible for the lather in shampoos and body washes. They're effective cleansers, almost too effective. Sulfates strip the skin of its natural oils, disrupt the skin's moisture barrier, and can cause dryness, redness, and irritation. They're also known to trigger eczema flares in sensitive skin.
This is especially problematic for babies, whose skin barrier is still maturing and depends on those natural oils to stay healthy and hydrated.
What to do: Look for washes and shampoos that use gentler, plant-derived cleansers such as coco-glucoside, decyl glucoside, or sodium cocoyl isethionate. These clean effectively without stripping the skin.
4. Phthalates
Also listed as: Often hidden under "fragrance" but can also appear as DEP, DBP, DEHP
Phthalates are plasticizing chemicals commonly used to make fragrance last longer on the skin. Like parabens, they are endocrine disruptors linked to hormonal disruption and developmental concerns in infants and young children. They are often not listed explicitly on product labels because they're considered part of a proprietary fragrance blend.
What to do: The most effective way to avoid phthalates is to avoid products containing synthetic fragrance altogether. You can also look for products that are certified phthalate-free or that carry clean beauty certifications.
5. Formaldehyde and Formaldehyde-Releasing Preservatives
Also listed as: DMDM Hydantoin, Imidazolidinyl Urea, Quaternium-15, Diazolidinyl Urea, Bronopol, 2-Bromo-2-Nitropropane-1,3-Diol
Formaldehyde is a known carcinogen. While it's rarely added directly to products in its raw form, a class of preservatives called formaldehyde-releasers slowly break down over time to release formaldehyde into the formula. These preservatives are still found in some baby shampoos, washes, and lotions.
What to do: Memorise or save the list of formaldehyde-releasing preservatives above they go by many names and aren't always easy to identify. Opt for products preserved with safer alternatives.
6. Mineral Oil
Also listed as: Petrolatum, Petroleum Jelly, Paraffinum Liquidum
Mineral oil is a byproduct of petroleum refining. It's cheap, widely available, and commonly used in baby oils and skin creams because it creates a barrier on the skin's surface. The problem is that it seals in, but doesn't nourish. It provides a temporary appearance of moisture while offering no actual skin supporting nutrients, and may interfere with the skin's natural functions over time.
Poorly refined grades of mineral oil are also classified as possible carcinogens by some regulatory agencies.
What to do: Swap mineral oil for truly nourishing plant-based oils: sweet almond oil, avocado oil, baobab oil, moringa oil, jojoba oil, sunflower seed oil, and fractionated coconut oil all offer similar barrier benefits while also delivering vitamins and fatty acids that support healthy skin development.
7. Alcohol (in Leave-On Products)
Also listed as: Ethanol, Isopropyl Alcohol, SD Alcohol, Denatured Alcohol
Short-chain alcohols are drying and can be very irritating on delicate skin. In rinse-off products, small amounts are generally fine. But in leave-on products like lotions, creams, and serums, alcohol can compromise the skin barrier and increase moisture loss; the opposite of what you want for baby skin.
Note: Not all alcohols are equal. Fatty alcohols like cetyl alcohol and cetearyl alcohol are actually emollients and skin-softeners, and are safe and beneficial. It's the short-chain drying alcohols listed above to watch out for.
8. Oxybenzone and Chemical Sunscreen Filters
Also listed as: Oxybenzone, Octinoxate, Homosalate, Octisalate, Octocrylene
This one is specifically relevant once your baby is old enough for sunscreen (most pediatricians recommend avoiding sunscreen on babies under 6 months, preferring sun-protective clothing and shade instead). Chemical sunscreen filters work by absorbing UV rays and converting them to heat, but several of these have been found to absorb into the bloodstream at significant rates and are linked to hormonal disruption.
What to do: When your baby is ready for sunscreen, choose a mineral sunscreen with zinc oxide or titanium dioxide as the active ingredient. These sit on top of the skin and physically block UV rays rather than being absorbed.
9. Talc
Also listed as: Talcum Powder, Talc
Talc has been used in baby powder for generations, but its safety has come under serious scrutiny. Talc can be naturally contaminated with asbestos, a known carcinogen, and loose powder of any kind poses an inhalation risk for babies. The American Academy of Pediatrics has recommended against using talcum powder on babies.
What to do: If you use a powder product in the diaper area, choose one made with cornstarch instead, and apply it away from your baby's face.
How to Read a Baby Product Label (Without a Chemistry Degree)
Reading ingredient lists (called INCI lists) can feel overwhelming, but a few simple habits make it much easier:
Go to the end of the list first. Preservatives and fragrance components are usually listed last. If you see "fragrance," "paraben," or any of the formaldehyde-releasing names near the end, put the product down.
The shorter, the better. A product with 8 ingredients is generally easier to vet than one with 30. Simpler formulas mean less opportunity for hidden irritants.
Look for third-party certifications. Labels like EWG Verified, MADE SAFE, or COSMOS Organic require brands to disclose and vet every ingredient. They're not foolproof, but they're a helpful shortcut.
Use the EWG Skin Deep database. The Environmental Working Group's free database (ewg.org/skindeep) lets you search any product or ingredient and see a safety rating based on available research. It's one of the most valuable tools a parent can have.
